C Sample Color Stream Viewer

Function description: Demonstrate using SDK to get color data and draw display, get resolution and set it, display color images, and exit the program through ESC_KEY key

| This example is based on the C High Level API for demonstration

Firstly, you need to create a Pipeline to connect the device and open color and depth streams

pipe = ob_create_pipeline( &error );

Create a Configuration to configure the resolution, frame rate, and format of color and depth streams

ob_config* config = ob_create_config( &error );

Configure streaming

//Configure Color streaming
ob_stream_profile *     color_profile = NULL;
ob_stream_profile_list *profiles      = ob_pipeline_get_stream_profile_list(pipe, OB_SENSOR_Color, &error);
//Search for the corresponding Profile according to the specified format, and prioritize the RGB888 format
color_profile = ob_stream_profile_list_get_video_stream_profile(profiles, 640, OB_HEIGHT_ANY, OB_FORMAT_RGB, 30, &error);
//If the RGB888 format is not found and does not match the format, search for the corresponding profile to open the stream
color_profile = ob_stream_profile_list_get_video_stream_profile(profiles, 640, OB_HEIGHT_ANY, OB_FORMAT_ANY, 30, &error);
error = nullptr;
ob_config_enable_stream(config, depth_profile, &error);  // Enable configuration

Start Pipeline through Configuration

ob_pipeline_start_with_config(pipe, config, &error);

Release resources and exit the program.

//Release frameSet
ob_delete_frame(frameset, &error);

//Release profile
ob_delete_stream_profile(color_profile, &error);

//Release profile list
ob_delete_stream_profile_list(profiles, &error);

//Release device
ob_delete_device(device, &error);

//Release pipeline
ob_delete_pipeline(pipe, &error);
